🔼The name Hara in the Bible
The name Hara occurs only once in the Bible. In 1 Chronicles 5:26 Hara is mentioned among the locations to which the Assyrians deported several tribes of Israel. This little list of locations is mentioned several times in the Bible (2 Kings 17:6, 2 Kings 18:11), but only the Chronicler mentions Hara.
🔼Etymology of the name Hara
The name Hara is possibly a transliteration of an Assyrian name or word, so it shouldn't be expected to mean anything in Hebrew. But as it is spelled it looks like it has to do with the word הר (har), meaning mountain:
The final letter א (aleph) does not relate to our noun הר (har), meaning mountain, but it could be regarded as prosthetic.
For a meaning of the name Hara, NOBSE Study Bible Name List reads Hill, and Jones' Dictionary of Old Testament Proper Names proposes Mountainous. BDB Theological Dictionary doesn't interpret this name.
